Module Types

Memory Section

• 18 x 30F Sense Amplifier Tends to fail short
• 5 x 33F Filter Module *“Most important single point of failure have been the capacitors for Vcore in the 33F modules whose schematic is very simple. I will unwrap the pins 8,9 on all these modules and connect external capacitors (100uF) on the mainboard to eliminate these completely (ref. Dr Erik Baigar’s Log)
  • Schematic (ref. Dr Erik Baigar)
• 15 x 47F Line Drivers - contain three address line gates & drivers, but only 40 of the 45 are used.

Logic and IO Sections

• __-Pu-Gy-Or Resistor Pack 6x 10Kohm
• __-Pu-__-Or Resistor Pack 5x 120ohm
• Gr-Bk-Yl-Or ? Related to power good
• Gr-Bu-Gr-Or Dual 4-input NAND gates/drivers DTL 932 d
• Gr-Pu-Or-Or Dual line driver “24 x sending outputs to the paper tape station on socket H and to the real-world (Jaguar) interface on plug C.”
